Specification of Letters Patent.

PatentedApr. 18, 1911.

Application filed January 21, 1908. Serial No. 412,029.

To all whom it may concern:

Be it known that we, HARRY M. ASHE,

subject of the King of Great Britain, and

NILLIAM D.-FRIoKs, citizen of the United States, respectively, and residents of Atlanta, Fulton county, State of Georgia, have invented certain new and useful Improvements in Type-W'riting Machines, of which the following is a specification.

The object of the present invention is to provide means forobtaining a copy on a single sheet or strip of paper of a part of each of the entries made on separate sheets of paper which are successively inserted in and removed from the machine. For instance, it is customary in certain systems of bookkeeping to enter nponthe monthly statement of customers from day to day the items chargeable against them, instead -0f entering these items in a ledger and then preparing the statements from the ledger. In carrying out this'systeni with our im-" proved typewriter, the original statement,

' which goes to the customer, and a copy,are

placed in the machine with a carbonsheet between, as is usual in making carbon dupli- 'cates. In addition we provide a third strip of paper, which is preferably in the form of a ribbon, and upon whichthe amounts of the items charged to the severalcustomers are entered in/a column. By summing up this 7 column at the end of the day, the total of all charges for the day is obtained. The strip upon which the totals are made, which may be termed a tally sheet, is preferably provided with a writing surface on one side and a carbon surface on the other, so that while the im ressions'are being producedbythe typewriter ribbon on the front of the tally sheet carbon impressions are produced on the statement at the back orv between the tally sheet and theplaten.

The various improvements comprised in the present invention will lee-described ineonnection with the accompanying drawingh tion is embodied; Fig. Q'isan'end elevation of the same; Fig. 3 is a sectiononthe line; 3-3 of Fig. 1 looking inlthe 'direction;indL-.;,

Our invention can be applied to typewriting machines without materially modifying their construction and without interfering,

with the ordinary operation of such machines. illustrated the invention as applied to the Well known L. C. Smith & Bros. typewriter and we have applied the invention without altering or modifying this typewriter excepting in one or two slight particulars which will be hereinafter pointed out.

Referring to the drawing, 10 indicates the frame of the typewriter, 11 the carriage, which runs on ball bearings 12, and 13-the platen. A frame or standard 14 issuitably connected to the right end of the carriage, as

In the present instance we have by a screw 15 and upon this frame are supported the majority of'the working parts constituting the present invention. On one arm of the frame is the supply spool 16 for the tally strip 17 and on another arm is mounted the receiving spool 18. The supply spool is mountedon a suitable shaft 19 and its movement is checked or retarded by a friction spring 20 which is interposed between the spool and the frame 14. v The receiving spool 18' is frictionally connected with a drive shaft 21 by means of a suitable spring 22, which maybe similar to the spring 20.

The 'tally strip is carried around the platen without contact with it excepting that it is directed close to the platen at'the print- :ing line and may, if desired. contact with it at this line. Referring vto F1'gg3'atw1ll-be1.

seen that that ally strip 17 is directed, down .ward from/the supply spnol over the paper table '23, a d/unde'rneath the usual shield 24. It is thence preferably carriedfaround the scale bar 2,5,1 and directly from said scale bar through the tally strip feed rolls to the receiving spool '18, passing close to the platen. at the printing line 26. To avoid carrying the'strip about an acute angle the scale bar '25 is preferablycutaway to some extent, as

illustrated .at 27, Fig.3.

We provide means for feeding creamy strip to space between lines of printing as ,Jtfollowsz Referring to'Figs'l, 2 and3 a train of gears 28,- 29* and 30 connect the receiving 'pool shaft 21-.with a feed'shaft'31 carry ing a ratchet wheel 32, the shaft 31.. be-

ing mountedlin suitable bearings, iinthe tally strip frame 14. A slide 33 is mounted to reciprocate on the tally strip frame adjacent to the ratchet wheel 32. AS shown, the slide 33 is sustained and guided by a rod 34 which passes through an opening in the frame l-land by the shaft 31 which passes through a slot 35 in the slide.' The. slide is normally held in its forward position by a spring 36. Upon the slide 33 is a pawl 37 arranged to cotiperate with the ratchet wheel 32, the said pawl being normally held against a pin 38 by a spring 39. It will be seen that when the slide 33 is pushed rearward the pawl 37 will engage the. ratchet wheel 32 and turn the shaft 31, thereby rotating the tally feed rolls 40, 41, the former- Y of which is fast on the shaft 31 while the that the spool shaft 21 is rotated somewhat faster than is necessary to wind up the strip, the spring 22 permitting the spool to slip on the shaft. In this way the strip is wound as fast as it is delivered by the feed rolls, whether the amount of strip on the spool is Y much or little.- It will be obvious that as the amount of strip on the spool grows the tendency will be to wind the strip faster.

As shown the feed roll 41 is pressed against the feed roll -by springs 42.

; On a bell crank 43 is carried the usual line feed pawl 44 which cooperates with the ratchet wheel 45 to turn the platen 13 to space between lines. The pawl 44' may be reciprocated to and from the'ratchet wheel by any suitable mechanism. As shown the pawl 44 is identical with that used on the typewriting machine referred to, with the' exception that it is provided withan upwardly extending arm 46 which is adapted normally rests on the ange 49 carried by a I to engage a finger 47 depending from the slide 33. The finger 47 is preferably hinged tothe slide 50- that it may be thrown up out o-fthe path of the arm 46, as indicated in dotted lines in Fig, 2. As is customary in typewriting machines, the pawl 44 is arranged to turn the ratchet wheel 45 differ? ent distances, according to therline spacing desired. As shown, a in 48. on the pawl 44 slide 50. The slide 50 is adjustable to and from the platen. When moved toward the platen it prevents the pawl 44 from dropping into engagement with the ratchet tooth until the travel of the pawl is nearly completed, with the result that the platen'is "moved but one tooth of the ratchet wheel.

The slide 50 may be withdrawnto effect the Through the gears 28, 29, and.

turning of the platen one, two, or more teeth of the ratchet wheel, as may be desired. The

slide 50. is held in any desired adjustment each time that the platen turning devices are' operated and that the tally strip will be moved a uniform amount each time regard:

.less of the amount that the platen is turned. 'In other words, the adjustment of the line space controlling slide 50 does not affect the extent of movement of the arm 46, and therefore does not affect the feed of the tally strip. This is important as it is desirable to feed the tally strip uniform amounts at all times regardless of the line spacing movements of the platen. We are enabled to feed the tally strip and the bills or other papers u on the platen different amounts by reason 0 the fact that the tally strip is independent throughout of the other papers in the machine and is not necessarily movable with them. r

Any desired number of sheets of paper,

printed on the tally strip. It will be understood thatto effect the printing of the figures on the outer sheet 54, the inner surface of the tally sheet is coated with carbon or other suitable marking substance. The sheets 53, 54, 55, are inserted in the machine and fed with the platen to space between lines in the ordinary manner, with the exception that we provide an adjustable paper guide 56 to locate the right margins of the sheets properly under the tally strip and to assist in inserting the paper in the machine.

As shown, the guide 56 is a folded sheet 1 metal construction substantially U-shaped in cross section having its rear lip straight and its forward .lip flared at the upper end. The guide is secured to a rod 57 which is ad justably secured to a hub or collar 58 on the frame 14. By means of a clamping screw 59 the paperguide maybe adjusted to the right or left and the right hand margins of the papers are thus made to register properly with the tally. strip.

It will be seen that'by means of a single paper guide of the form just described, the right-hand margins of papers will be maintained in alinement with the. corresponding margins of the tally strip. vVith this improved guide it is unnecessary to provide any means for-guiding the left-hand margins and by reason of the particular cross sectional form of the guide any bending or vcurving of the paper at the guiding edge is prevented. Another advantage of the present construction is that as the guide is attached to and carried directly by the carriage frame, it leaves the er shelf entirely free and unobstructed.

Referring to Figs. 5, 6 and 7 the platen is provided with a-fixed shaft or trunnion 60 and with a shaft 61 which is adapted to rock relatively with the platen. The shaft 61 ex- .tends through the right end of the platen and has a bearing at or near the left end thereof and it is adapted to turn in the right head block or plate 62v of the platen. The shaft 61is providedwith shoulders 63 which cooperate with the pin 64 to limit the movement ofthe shaft, and it is normally held in one extreme position by a spring 65 which is coiled about, the shaft and engages the head block 62 and a collar 66 on the shaft. ,The ratchet wheel is in the form of a ring mounted on; an annular flange 67 on the head block 62. Normally. the

ratchet ring 45 is clamped to, the head block away from the ratchet ring 45,.thus freeing the platen from its ratchet. The platen may then be adjusted backward or forward in dependently .of the ratchet, which latter is normally held stationary by the usual holding .pawL' These devices which permit .of rotating the platen independently .of. its ratchet wheel are very useful in connection with the tally strip attachment as they permit the statements orother documentswhich are inserted in the carriage to be" adjusted with respect to the printing line to bring any --desired line on the paper into position for printing. ments are repeatedly placed in the machine to enter items from day to day and it'is desirable to be able to adjust the platen so that successive items of printing can be vplaced on the paper in conformity with preceding items.

Theoperation ofthe invention will be understood from theforegoing description and need only be briefl referred to.

' It'will be understood that the tally strinj attachment 'can be placed on the machine mthout making any material 7 change in the 1 latter and that the machinecan be used for In many establishments state- &

ordinary purposes, such as correspondence, at any time either with the attachment on or off. The paper guide 56 should be adjusted so as to bring the right margins of the statements or other documents to be printed into proper relation with the tally strip, the object being to secure the printing of the totals or other figures which are to appear on the tally-strip in the right positions both on the tally strips and the statements or other papers. When the paper guide is properly adjusted, statements or other documents. may be inserted in and removed from the machine as frequently as desired without in any Way disturbing the tally strip and all figures printed on the right margins of the said statements, etc. will appear on the tally strip also, The

tally strip may be fed forward once either when taking out a paper or when inserting a new one, but it requires no other attention. Preferably the statement is inserted so that the last item is at the writing line of last entry,and then the tally strip and platen is spaced with one operation. \Ve preferably locate one of'the usual paper fingers 71 at the right of the platen and the pressure roll 72 on said finger may extend under the tally strip if desired, as shown in Figs. 1 and 3. I

It will be noted that the tally strip feeding means can be operated independently of the platen rotating means by simply pushing rearward the slide 33. It is convenient however to operate the tally feeding means automatically each time the platen rotating means are operated and for this purpose the arm 46 is provided on the line'feed pawl and the finger 47 on the telly feed slide.

In this application only so much of the typewriting machine has beendesc'ribed as is.

necessary to a full understanding of the present invention; It has been thought unnecessary for instance to describe in detail the paper feedingdevices, which are of ordinary construction. These devices include the paper finger 71 and feed rolls 73, 74, indicated in dotted lines inFig. 3.

It will beevident that our invention may be embodied in various mechanical forms and We do not therefore desire to'be understood as limiting ourselves to the precise construction and arrangement ofparts illustrated and described. For instance, the paperguide 56 may in. some instances'be connected with, or integral with the paper table 23, in which case we would make the papefltable'adjustable to the right or left in or er to adjust the paper for. the proper margin...

'Nojclaim is made to the particular construction of platen and meansconnectin the ratchet therewith, hereinbefoi'e describe 'Bythe term tally strip therein employed is meant a relatively narrow strip or ribbon of paper on which only a comparatively short line of writing can be produced and which strip is to be clearly distinguished from a sheet adapted to extend throughout the greater portion of the length of the typewriter platen and on which lines of considerable length; as the details of items of a bill, can be written.
